-Well, actually, it depends on what you mean by "life."
-
-A true, hard failure in a CRT (i.e., it simply doesn't work anymore) IS
-fairly rare.  But CRT lifetimes are generally quoted in time to half-bright.
-You may not consider half the original brightness to be a "failure", as it
-happens so gradually that most folks won't notice it UNTIL they put a new
-unit next to the old one.  But the typical tube reaches this point in
-something like 10k-20k hourse, whereas there's no reason that the rest of
-the monitor (if designed properly) shouldn't have at least a 40k-50k MTBF.

What is the mechanism that degrades crt brightness?  Is is phosphor
related?  Electron gun related?  If I leave my monitor on with the
brightness turned all the way down, will that prolong the brightness
half life of the tube?
